Answer:
x = 3.46 units
Step-by-step explanation:
Given:
angle RQS = 60
QS = 2 units
PS = 8 units
To Find:
RS = x = ?
Solution:
In triangle QRS,
tan angle Q = RS / QS
tan 60 = x / 2
root 3 = x / 2
x = 2 root 3
x = 2 x 1.73
Therefore, x = 3.46 units

You use it during your life spand
Let the number of bike be x and the number of skates be y, then
21x + 20y ≥ 362 . . . (1)
2y = x . . . (2)
Putting (2) into (1), then
21(2y) + 20y ≥ 362
42y + 20y ≥ 362
62y ≥ 362
y ≥ 5.84
The least number of pairs of skates they need to rent each day to make their minimum is 6.
Divide 50 by 1 3/4 to get your answer for miles per minute then multiply that by sixty to get hours. then write it as _mph
